In my experience this doesn't always work, I used to connect from work
to home and vice versa using ssh and the keep alive option din't keep
those sessions connected.  I ended up with a trivial program running in
the background that sent NUL characters at five minute intervals.

I think in my case it may have been some firewall/router timeout that
was disconnecting the idle connections.
